A Quick Background
Either black and white or colored CCTV security cameras both have their distinctive advantages for your video camera surveillance requirements. Color security cameras have very evident advantage of giving excellent color feature. It has the capacity to capture the color details of a criminal’s skin tone, clothing, or vehicle. This is actually very advantageous in solving the crime and prevent the criminals to break lose. As image is produced, IR cut filter is positioned over the imager In order for color security cameras to accurately create colors. The cut filter permits the camera to only see light in the visible spectrum (400nm to 750nm). As a result, color surveillance cameras fails when it comes to creating important images in not so lighted scenes.
On the contrary, black and white video camera surveillance setups don’t have an IR cut filter because they are intended to interpret color. Without the filter, B…W CCTV camera options can utilize other light frequencies like infrared. Infrared which come from a numerous sources, including the sun, fluorescent lights, incandescent lights and especially infrared illuminators. Consequently ,B…W surveillance cameras operates notably better in low light and some can see at light levels 0.0001 lux which is almost complete darkness. Other advantage of B…W video surveillance cameras is the ability to illuminate an area with IR. It provides the camera with sufficient lighting but gives natural darkness which can help in suspects’ arrest.
More about Day/Night Cameras Can give
Day/Night security cameras offer the unique advantages of both color and black and white CCTV camera setups. D/N video security cameras work just like color cameras during the day and switch to a B…W mode at night, using a removable IR cut filter. As daylight fades, day/night cameras sense the lower light levels and mechanically remove the IR cut filter, instantly switching to a more sensitive black and white mode.
Day/night surveillance cameras are available in all shapes and sizes to meet virtually every application need. D/N technology is available in many form factors such as dome cameras, fixed cameras, bullet cameras and even in tiny board cameras – which are especially useful for undercover operations which typically happen in a wide variety of lighting conditions. Many day/night CCTV cameras also offer built in infrared illumination, making a very nice turn-key camera package.
D/N security cameras are referred as the conventional and most successful is called the true day/night cameras, and uses a detachable mechanical cut filter, as explain above. Though, digital day/night cameras (or electronic day/night cameras) are also offered in the market, which electronically regulate colors daytime, as a substitute of using an infrared filter. With the use of this, digital day/night cameras carryout advantage of true day/night cameras, although at a cheap price.When physical filter is no longer necessary, digital day/night technology can be converted to smaller types factors, such as bullet cameras.
Regardless of the type of day/night camera you choose, I recommend considering the following areas to ensure you get the very best solution for your application:
1. Lux ratings – Unlike conventional cameras, day/night cameras normally have two lux ratings – one for the camera’s color mode, and one for its black and white mode. Considering both will let you to get useful evaluation between day/night and more familiar customary CCTV cameras.
2. Lenses – If you are buying a fixed security day/night camera that requires a C- or CS-mount lens, be sure to get a CCTV camera lens that is rated for use with infrared light. IR ready camera lenses allow for the proper passage of IR light, the full use of the camera’s day/night capabilities, and of course, lower light performance.
3. S/N Ratio – There are many surveillance cameras in the market place with low lux ratings, but this does not always mean they will produce a good picture in low light. To ensure you get both, select a security camera with a signal-to-noise ratio of 48dB or higher
Video camera surveillance can be an competent tool and is utilized in many environments. Employing video surveillance systems can have many very positive effects. Get a totally unique version of this article from our article submission service
